Your objective is to find treasures in the cave while avoiding and killing an
immense amount of living jelly. Caves are randomly generated and are harder
the deeper they are. They have various levels (potentially infinite) and contain
a number of chests.

The main obstacle of the game are jelly monsters. By digging around the map, you
get rocks that can later be thrown at these monsters to kill them. There's not
much more to the game, though.
